The single step CADO process is capable of converting vapor of wet ethanol into hydrocarbon blendstocks competitively priced at $2/gigajoule that can be blended with gasoline, diesel, or jet fuels to diminish emissions of greenhouse gases.
The conversion procedure of fuel uses zeolite, a kind of catalyst, to create actual loner chains of hydrocarbons from ethanol (alcohol). The process substitutes the traditional multi-step processes and uses less energy.

ORNL worked with technology licensee Vertimass and researchers at 10 other institutions on a technoeconomic and a life cycle sustainability analysis of the process -- single-step catalytic conversion of ethanol into hydrocarbon blendstocks that can be added to jet, diesel, or gasoline fuels to lower their greenhouse gas emissions. This new technology is called Consolidated Dehydration and Oligomerization (CADO).CADO.
The analysis, published in Proceedings of the National Academy of Sciences, showed that this single-step process for converting wet ethanol vapor could produce blend-stocks at $2/gigajoule (GJ) today and $1.44/GJ in the future as the process is refined, including operating and annualized capital costs. Thus, the blend-stock would be competitive with conventional jet fuel produced from oil at historically high prices of about $100/barrel. At $60/barrel oil, the use of existing renewable fuel incentives result in price parity, the analysis found.
The conversion makes use of a type of catalyst called a zeolite, which directly produces longer hydrocarbon chains from the original alcohol, in this case ethanol, replacing a traditional multi-step process with one that uses less energy and is highly efficient. The conversion operation could be integrated into new biofuels plants or installed as bolt-on technology to existing ethanol plants with minimal new capital investment, the researchers noted.
The project was supported by the Center for Bioenergy Innovation at ORNL, which in turn is supported by the DOE Office of Science. Scale-up R&D were supported in part by the DOE Office of Energy Efficiency and Renewable Energy and by Vertimass.

Existing US ethanol production plants currently have the capacity to produce approximately 16 billion gpy, a level that saturates current use as 10 pct blends with gasoline. However, the new Vertimass catalyst breaks that barrier by producing a hydrocarbon that can be blended at much higher levels. In addition, while ethanol has been traditionally considered too low in energy density for use as a jet fuel, the Vertimass catalyst can overcome that issue.
Initial tests indicate the Vertimass fuels (Vertifuels) are compatible for blending with gasoline, diesel, and jet fuels with no engine modifications, but further tests are underway for ASTM certification.
Vertimass is working with the University of Dayton Research Institute (UDRI), Sandia National Laboratory (SNL), TechnipFMC, and the University of California, Riverside (UCR).

Vertimass believes their technology of converting sustainable ethanol into fungible gasoline, diesel, jet fuel blend stocks and the chemical building blocks benzene, toluene, and xylene (BTX) can substantially increase corn demand in the US. This innovative technology eliminates the ethanol blend wall that currently limits ethanol use and allows for further expansion of renewable fuels and chemicals while maintaining a low greenhouse gas footprint.
According to Vertimass, "This innovative technology will be fully applicable to conversion of ethanol from cellulosic biomass such as agricultural residues and dedicated energy crops and sugars into BTEX and hydrocarbon fuels as it is to corn ethanol."

According to Vertimass, BETO's verification paves the way for a demonstration scale of the technology for converting sustainable ethanol into fungible gasoline, diesel, and jet fuel blend stocks and the chemical building blocks benzene, toluene, and xylene (BTX). This new Vertimass pathway can enhance use of biomass-derived renewable fuels that lower greenhouse gas emissions and allow ethanol producers to expand their product portfolio. The Vertimass systems can be added to existing ethanol producers' facilities at fractions of the cost of a new facility, according to the company.
